Single/Dual/Quad, Low-Cost, Single-Supply,
Rail-to-Rail Op Amps with Shutdown
General Description
The MAX4400–MAX4403 low-cost, general-purpose op
amps offer Rail-to-Rail^® outputs, draw only 320µA of qui-
escent current, and operate from a single +2.5V to +5.5V
supply. For additional power conservation, the MAX4401
offers a low-power shutdown mode that reduces supply
current to 1µA max and puts the amplifier’s outputs in a
high-impedance state. These devices deliver ±1.4mA of
output current and are unity-gain stable with a 1MHz gain-
bandwidth product driving capacitive loads up to 400pF.
The MAX4400–MAX4403 are specified to +125°C, making
them suitable for use in a variety of harsh environments,
such as automotive applications.
The MAX4400 single amplifier is available in ultra-small
5-pin SC70 and space-saving 5-pin SOT23 packages.
The single MAX4401 includes the shutdown feature and is
available in a 6-pin SC70. The MAX4402 is a dual amplifier
available in 8-pin SOT23 and SO packages. The
MAX4403 quad amplifier comes packaged in a 14-pin
TSSOP or SO.
